Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 225mm stroke, 1/4" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S
Needing a trim range wider than most jobs ever use, the MACJ63X225-100S pairs a 63 mm bore with a 100 mm adjustable window on its extend stroke. Air drives the piston both ways, and the variable cushion at each end absorbs the shock of a 1558 N push at 0.5 MPa, so heavier loads can travel at up to 800 mm/s without denting the covers. Inside, a stainless-steel barrel and a hard-chrome plated carbon-steel rod resist the washdown and damp air that wreck painted minis.
For sizing, bank on roughly 935 N of real work at 0.5 MPa rather than the full 1558 N rating; halving the 159 kgf theoretical lift still moves about 79 kg vertically with margin to spare. The magnet comes standard - position feedback needs only a CMSG, DMSG or EMSG switch snapped onto the barrel.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S Is Used
Case-drop gate on a canning line
Releasing stacked cases toward a palletizer demands about 935 N of real push at 0.5 MPa; the 100 mm window absorbs late line changes without re-piping.
Stone slab pusher in a cutting shop
Wet cutting benches spray water constantly, so the stainless barrel and chrome-plated 16 mm rod keep the 225 mm stroke moving without rust seizure.
Bin ejector under a sorter
Kicking full collection bins off a chute uses the full 1558 N push, and DMSG switches on the standard magnet confirm each ejection to the PLC.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S the Right Cylinder?
Step down to bore 50 (981 N push at 0.5 MPa) if the load needs under about 590 N of work; nothing in the MA range is larger than 63 mm. The stop screw only sets the extend stroke - on air loss the piston drifts freely, so it is not a load-holding brake. FA flange and LB foot mounts plus I or Y knuckles cover the usual fixings, and the standard magnet pairs with CMSG, DMSG or EMSG switches. With 225 mm of travel, guide any off-axis load separately to protect the rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-100S FAQ
Its round barrel is stainless steel, the rod is carbon steel hard-chrome plated to 20 um, and the aluminium-alloy covers are rolled onto the tube for a riveted, sealed body. That build tolerates washdown and humidity, while the variable air cushion at both ends removes end-of-stroke shock even at high speed.
Push at 0.5 MPa is 1557.9 N and pull 1457.4 N; at 0.7 MPa the cylinder reaches 2181 N push and 2040 N pull, peaking at 317.7 kgf theoretical at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the 100 mm adjustable window trims the extend stroke on site.
